BACK EXTENSION 4000

Start position
1. Adopt the right exercise position. Sit on the seat. Your upper body (back straight)
leans on the chest padding. Place your feet on the footrests (feet about shoulder
width apart) and grasp the lateral handlebars with your hands (see also Chapter
5.4).
2. Now contract the torso muscles and press your straight upper body backwards
against the backpad until you are sitting upright. Make sure not to hyperextend
your upper body and to keep your pelvis in a stable position. Breathe out when
you exert strain against the resistance. Maintain this position momentarily.
3. Now lower your upper body forwards again, making sure to maintain control.
Stop the return motion in time so that your torso does not sag downwards.
Breathe in during the return sequence
